Description

Technical Field

[0001] This utility model belongs to the field of cotton planting technology, specifically a delinting device for cotton seed processing. Background Technology

[0002] In current cotton seed processing, it is necessary to remove residual lint from the surface of cotton seeds to facilitate subsequent processing or sowing. Currently, two common methods are used to remove residual lint from the surface of cotton seeds: one is acid delinting, which mainly uses strong acids such as sulfuric acid to carbonize and brittle the residual lint on the surface of the seeds, causing it to fall off; the other is a physical method that forcibly removes the residual lint from the surface of the seeds. This method requires the use of a cotton seed delinting machine, which generally consists of feeding, delinting, seed discharge, lint collection, and adjustment mechanisms. The cotton seeds come into contact with and rub against rough delinting rollers, scraping and hooking off the residual lint on the cotton seeds before the seeds are discharged from the seed discharge port. In existing cotton seed delinting machines, after delinting, the delinted cotton seeds and residual lint are mixed together and discharged from the seed discharge port. A large amount of residual lint accumulates, has poor flowability, and if not cleaned in time, it will pile up at the seed discharge port, clogging the feed pipe and affecting the normal operation of the cotton seed delinting machine. Therefore, it is necessary to design a cotton seed processing delinting device that avoids residual lint clogging the feed pipe. Utility Model Content

[0003] The purpose of this invention is to provide a cotton seed delinting device that avoids residual lint clogging the feed pipe, thereby solving the problem that in existing cotton seed delinting machines, residual lint accumulates in the cotton seeds after delinting, clogging the feed pipe and causing the cotton seed delinting machine to malfunction.

[0004] To solve the above technical problems, the technical solution of this utility model is as follows: a delinting device for cottonseed processing, including a processing cylinder and a collecting box. The processing cylinder has a feed inlet at its upper end and a seed discharge outlet at its lower side. A delinting roller is rotatably connected inside the processing cylinder. A guide plate is fixedly connected to the outer side of the upper end of the delinting roller. The delinting roller is hollow inside, forming a cavity. A connecting pipe is fixedly connected to the lower end of the cavity. The lower end of the connecting pipe extends out of the processing cylinder and is connected to a rotary joint. The upper end of the collecting box is connected to the other end of the rotary joint through a pipe. Several through holes are opened on the side wall of the delinting roller. The delinting roller is driven by a motor. An air extraction mechanism is connected to the lower side of the collecting box.

[0005] Furthermore, the air extraction mechanism includes a blower and an air extraction pipe. One end of the air extraction pipe is fixedly connected to the lower side of the lint collection box, and the other end is fixedly connected to the input end of the blower. A filter screen is fixedly connected to the lower side of the lint collection box, and a cleaning door is hinged to one side of the lint collection box. The connection position of the air extraction pipe is located below the filter screen.

[0006] Furthermore, both the upper and lower ends of the delinting roller are rotatably connected to the inner wall of the processing cylinder via rotating shafts. The motor is fixedly connected to the top of the processing cylinder. The upper rotating shaft of the delinting roller is fixedly connected to the output end of the motor. The lower rotating shaft of the delinting roller has a hollow structure and is sleeved and fixedly connected to the outside of the connecting pipe.

[0007] Furthermore, both the processing cylinder and the delinting roller are cylindrical in shape. The inner diameter of the processing cylinder is larger than the outer diameter of the delinting roller. The bottom center of the processing cylinder protrudes upward to form a conical surface. The outer side of the upper end of the delinting roller is inclined. The guide plate is fixedly connected to the outer side of the inclined surface at the upper end of the delinting roller.

[0008] Furthermore, two scrapers are fixedly connected to the bottom of the delinting roller. The two scrapers are symmetrically arranged, and the lower end of the scrapers is in contact with the bottom of the inner side of the processing cylinder.

[0009] Furthermore, at least two guide plates are provided, and multiple guide plates are evenly distributed around the outer edge of the inclined surface at the upper end of the delinting roller.

[0010] Furthermore, a feed hopper is fixedly connected to the upper end of the feed inlet, and a discharge pipe is fixedly connected to the outer end of the seed discharge outlet.

[0011] Furthermore, a support frame is fixedly connected to the bottom of the processing cylinder, and the lint collection box and the air extraction mechanism are both fixedly connected to the upper end of the support frame.

[0012] This utility model has the following advantages compared with the prior art:

[0013] 1. This utility model involves creating through holes and an internal cavity on the delinting roller. An induced draft fan connects to the cavity, continuously drawing air from it. This causes the residual fibers removed from the cotton seeds to enter the cavity through the through holes along with the airflow. The residual fibers are then separated and collected by the fiber collection box. This significantly reduces the amount of residual fibers mixed in with the falling delinted cotton seeds, preventing the accumulation of residual fibers at the seed discharge port and avoiding blockage of the unloading pipe that would affect normal use.

[0014] 2. This utility model provides a scraper at the bottom of the delinting roller that is compatible with the bottom of the processing cylinder. This scraper moves the cotton seeds falling to the bottom of the processing cylinder and sends them to the seed discharge port, making it easier for the cotton seeds to be discharged from the processing box. By providing a guide plate at the upper end of the delinting roller, the cotton seeds to be delinted can be assisted in being fed into the gap between the processing cylinder 1 and the delinting roller 5, avoiding the device from running idle and improving the delinting efficiency of the device.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figures 1 to 4 The cottonseed delinting device shown includes a processing cylinder 1 and a collecting box 2. The processing cylinder 1 has a feed inlet 3 at its upper end and a seed discharge outlet 4 at its lower side. A delinting roller 5 is rotatably connected inside the processing cylinder 1. A guide plate 6 is fixedly connected to the outer side of the upper end of the delinting roller 5. The delinting roller 5 is hollow, forming a cavity 7. A connecting pipe 8 is fixedly connected to the lower end of the cavity 7. The lower end of the connecting pipe 8 extends out of the processing cylinder 1 and is connected to a rotary joint 9. The upper end of the collecting box 2 is connected to the other end of the rotary joint 9 through a pipe. Connected to the outside, the delinting roller 5 has several through holes 10 on its side wall. The gap between the outer side wall of the delinting roller 5 and the inner side wall of the processing cylinder 1 is larger than the particle size of the cotton seeds, allowing the cotton seeds to enter the gap when the delinting roller 5 rotates. Scraping blades are installed on both the outer side wall of the delinting roller 5 and the inner side wall of the processing cylinder 1. When the delinting roller 5 rotates, the scraping blades on both sides cooperate to scrape off the residual fibers from the cotton seeds. The delinting roller 5 is driven by a motor 11, and an air extraction mechanism is connected to the lower side of the fiber collection box 2. The air extraction mechanism continuously draws air from the cavity 7, drawing the residual fibers removed from the processing cylinder 1 into the cavity 7 through the through holes 10. The residual fibers follow the airflow through the connecting pipe 8 and are finally filtered and collected in the fiber collection box 2.

[0022] To extract gas from cavity 7 and create negative pressure, allowing gas from outside cavity 7 to enter through through hole 10, the extraction mechanism includes a blower 12 and an extraction pipe 13. One end of the extraction pipe 13 is fixedly connected to the lower side of the lint collection box 2, and the other end is fixedly connected to the input end of the blower 12. A filter screen 201 is fixedly connected to the lower side of the lint collection box 2, and a cleaning door 202 is hinged to one side of the lint collection box 2. The extraction pipe 13 is connected below the filter screen 201. Residual lint enters the lint collection box 2 with the airflow, is filtered by the filter screen 201, and remains in the lint collection box 2. The cleaning door 202 is opened periodically to clean and remove the residual lint collected in the lint collection box 2.

[0023] In order to drive the delinting roller 5 to rotate, thereby cooperating with the scraping blades on the inner wall of the processing cylinder 1 to scrape off the residual fluff on the cottonseed, both the upper and lower ends of the delinting roller 5 are rotatably connected to the inner wall of the processing cylinder 1 through rotating shafts. The motor 11 is fixedly connected to the top of the processing cylinder 1. The upper rotating shaft of the delinting roller 5 is fixedly connected to the output end of the motor 11. The lower rotating shaft of the delinting roller 5 has a hollow structure and is fixedly connected to the outside of the connecting pipe 8.

[0024] To make better use of space, both the processing cylinder 1 and the delinting roller 5 are cylindrical. The inner diameter of the processing cylinder 1 is larger than the outer diameter of the delinting roller 5. To facilitate the discharge of cotton seeds with residual fibers from the discharge port 4, the bottom center of the processing cylinder 1 is raised upward to form a conical surface. The discharge port 4 is located on the outer side of the bottom of the processing cylinder 1. The cotton seeds fall onto the conical surface at the bottom of the processing cylinder 1 and move along the inclined conical surface to the discharge port 4, from which they are discharged out of the processing cylinder 1. The outer side of the upper end of the delinting roller 5 is inclined, and the guide plate 6 is fixedly connected to the outer side of the inclined surface at the upper end of the delinting roller 5.

[0025] To ensure the delinting cotton seeds are discharged from the seed outlet 4 and to prevent them from accumulating at the bottom of the processing cylinder 1, two scrapers 15 are fixedly connected to the bottom of the delinting roller 5. The two scrapers 15 are symmetrically arranged, with their lower ends in contact with the bottom inner side of the processing cylinder 1. When the delinting roller 5 rotates, the two scrapers 15 rotate accordingly, agitating the cotton seeds located at the bottom of the processing cylinder 1 and moving them to the seed outlet 4 for easy discharge from the processing cylinder 1.

[0026] To facilitate the feeding of cotton seeds to be delinted into the gap between the processing cylinder 1 and the delinting roller 5, at least two guide plates 6 are provided, with multiple guide plates 6 evenly distributed around the outer edge of the inclined surface at the upper end of the delinting roller 5. As the delinting roller 5 rotates, the guide plates 6 move accordingly. The inclined guide plates 6 agitate the cotton seeds located at the upper end of the delinting roller 5, assisting the cotton seeds in entering the gap between the processing cylinder 1 and the delinting roller 5 for delinting.

[0027] To facilitate feeding and unloading of the device, a feeding hopper is fixedly connected to the upper end of the feeding port 3, and a discharge pipe is fixedly connected to the outer end of the seed discharge port 4.

[0028] To support the device and improve its overall stability, a support frame 14 is fixedly connected to the bottom of the processing cylinder 1, and the lint collection box 2 and the air extraction mechanism are both fixedly connected to the upper end of the support frame 14.

[0029] The specific working process of this utility model is as follows:

[0030] Start the motor 11 and the blower 12. The motor 11 drives the delinting roller 5 to rotate, and the blower 12 continuously draws air from the cavity 7. The cotton seeds to be delinted are added to the processing cylinder 1 from the feed port 3. Under the guidance of the guide plate 6, the cotton seeds continuously enter the gap between the processing cylinder 1 and the delinting roller 5. After delinting, the cotton seeds finally fall to the bottom of the processing cylinder 1 and are discharged from the discharge port 4 under the action of the scraper 15. During the delinting process, under the action of the blower 12, the scraped residual fibers follow the airflow through the through hole 10 into the cavity 7, and then enter the collection box 2 through the connecting pipe 8 and the rotary joint 9. The residual fibers are blocked by the filter screen 201 and remain in the collection box 2. The airflow is drawn out by the blower 12 through the exhaust pipe 13, separating the residual fibers from the cotton seeds and preventing the residual fibers from accumulating at the discharge port 4 and blocking the discharge pipe.
